Answer:
55/2574 ≈ 2.18%
Step-by-step explanation:
There are a total of 13 people on the council.
The probability that the first person is a Democrat is 8/13.
The probability that the second person is a Democrat is 7/12.
The probability that the third person is a Republican is 5/11.
The probability that the fourth person is a Republican is 4/10.
The probability that the fifth person is a Republican is 3/9.
The total probability is:
P = (8/13) (7/12) (5/11) (4/10) (3/9)
P = 56/2574
P ≈ 0.0218
There is a 2.18% probability of selecting two Democrats and three Republicans.
Answer:
Step-by-step explanation:
Given that the dollar cost of producing x appliances is
A) Average cost can be obtained by dividing c(x) by units = x
i.e. average cost = 
B) Marginal cost = dC/dx = 
When x=140 marginal cost 
C) We calculate
c(140) = 
c(141) = 
Marginal cost = difference = 33.80
Same as 34 shown in marginal cost.
Answer:
18
Step-by-step explanation:
you are dividing so you have to divide both sides by 5 which will get you to 18
Answer:
Step-by-step explanation:
if you use a graphing calculator you we see that the smaller the leading coeffient the wider the parabola.
or use a table and plug in values for y for each x
y = x² 5x² 15x²
x = 1 1 5 15
x = 2 4 20 60
y is larger for a larger ax² a coeffient
so the is more narrow for a higher coeffient
f(x) = 5x² has the smallest coeffient so the widest parabola
